The invention discloses a double-liquid rotary inner-spraying type agricultural greenhouse film and a production process thereof. In the process for blow-molding polyolefin films, a double-liquid rotary inner-spraying device is used to spray two prepared spraying liquids A and B in a film bubble in a rotary manner through two liquid pipes mounted inside the film bubble, wherein the surface layer of the film bubble is evenly coated with the spraying liquid A; the surface layer thereof coated with the spraying liquid A is further evenly coated with the spraying liquid B; and then, the excessive moisture is evaporated by the temperature of the film bubble per se to form a dense film on the film bubble, thus obtaining the double-liquid rotary inner-spraying type agricultural greenhouse film having longer dripping fog-eliminating duration. The obtained product of the invention achieves the effects of long dripping fog-eliminating duration and high transparency, thus favoring the growth and development of crops; and the double-liquid rotary inner-spraying type agricultural greenhouse film not only relieves the disease and improves the yield and quality of crops, but also reduces the cost for crop field management and increases the income of the farmers.
